It's interesting, but tries to cover too much subject matter in the space of 23 minutes. In particular, the first guest speaks very fast trying to say as much as possible. "Intergrated Software" and Graphical User Interfaces are simply too big of a subject to be discussed in the space of 23 minutes.
Still , there are some interesting moments in the episode. The ideas discussed are taken for granted today, but were still fairly novel at the time.
